Hi
I'm trying to replace the rocker switches in my car for some push buttons. I have asked the manufacturer of the switches I have chosen if they do them as a latching type, but they don't. So here is my Dilema :? .
Each circuit will have only one momentary push button and the circuits need to latch. :shock:
I have a rear fog light that needs to come on when the button is pressed and go of when the button is pressed a second time. I assume that the circuit will first drive a relay, that will in turn supply the fog light.
The second circuit wil operate as follows.
Push button press 1 - Fan speed 1 signal sent to relay.
Push button press 2 - Fan speed 1 and 2 sent to relays.
Push button press 3 - All fan signals removed.
Any diagrams or advice would be much appreciated.
:?: Some questions.
Does the resistance of the automotive relay play any part in the design of the circuits?
Am I right saying that the circuit will also need a debounce circuit?
Do you think that standard relay contacts would suffer from making and breaking with the vibrations from a car? Is that why we have automotive relays because they are designed to be able to cope with this?
Can you suggets a good book to start off with learning anout digital electronics that wil take you through from complete beginner to moderate. So that I could be able to design this circuit myself in the future?
Thanks for taking the time to read this post
